Hello! Need some advice?

I am new to myfitnesspal I guess, and I'm a part of caloriecount as well. I was wondering what people thought of both sites because when I log my intake of food on here it will say I've gone over the amount of calories I should eat a lot (whoopsie!), and when I log in my intake over at caloriecount it will say I've got like 700 calories left over. I was just wondering how this could happen since I'm putting in the exact same information???
